A Five-Dimensional "Spider-Web" Strategy for Quality Markers Identification of Traditional Chinese Medicine Compound Preparations Based on an Integrated Characteristic Network.
Article in Journal of separation science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Given the complex composition of traditional Chinese medicine (TCM) formulas, quality evaluation cannot rely on a single component or a limited few. Therefore, a five-dimensional quality marker (Q-marker) identification system encompassing "effectiveness, specificity, transferability, measurability, and formula compatibility" was developed and subsequently applied to Fufang Huangqi Jianpi oral liquid (FFHQJPOL) as an example. Using UHPLC-Q-TOF/MS, 62 compounds were identified in the preparation. The measurability dimension was constructed based on 17 major constituents derived from 23 common peaks in the chromatographic fingerprints of 10 batches. Serum pharmacochemistry via UHPLC-Q-TOF/MS revealed 32 prototype components absorbed into the bloodstream, thereby establishing the transferability dimension. Network pharmacology approaches were applied to construct a "component-target-disease-pathway" network, defining the effectiveness dimension. A topological network of compounds and herbs was established to depict the distribution pattern of the candidate compounds across various herbs, thereby revealing specificity. The compound compatibility dimension was established based on the function and proportional weight of its active ingredients in the formula. Ultimately, through regression area (RA) and coefficient of variation (CV) calculation, 3-hydroxy-9,10-dimethoxypterocarpan, ononin, zizyphusine, calycosin-7-O-glucoside, and sinapine were initially identified as the key Q-markers. It is worth mentioning that astragaloside IV and astragaloside II were additionally incorporated into the Q-markers system based on UHPLC-Q-TOF/MS analysis and their known pharmacological activities, ultimately establishing seven key Q-markers for FFHQJPOL. This strategy provided a multi‑dimensional integrated paradigm for Q‑markers discovery in TCM compound preparations, facilitating the transition from single‑index to system‑integrated quality control.
